AN EVALUATION OF GRAVELS FOR USE IN LIME-FLY ASH-AGGREGATE COMPOSITION

THE RESULTS ARE PRESENTED OF A LABORATORY STUDY OF THE EFFECTS OF GRADATION, HARDNESS, SOUNDNESS AND SILT-CLAY CONTENT OF GRAVELS WHEN THE GRAVELS ARE USED IN LIME-FLY ASH COMPOSITIONS. DURABILITY AND COMPRESSIVE STRENGTH TESTS ARE USED AS THE BASIS FOR EVALUATION. AN ATTEMPT IS MADE TO ESTABLISH A CORRELATION BETWEEN THE VARIABLES AND THE ANTICIPATED FIELD PERFORMANCE OF THE COMPOSITIONS. STANDARD CYLINDRICAL SPECIMENS (4 IN. DIA. X 4.59 IN. HIGH) WERE PREPARED FOR DIFFERENT NATURAL GRAVELS MIXED WITH OPTIMUM PERCENTAGES OF HYDRATED LIME AND FLY ASH. SPECIMENS WERE ALSO MOLDED USING ONE GRAVEL TO WHICH VARYING AMOUNTS OF FINES WERE ADDED ALONG WITH THE LIME AND FLY ASH. AFTER SUITABLE CURING PERIODS TESTS FOR UNCONFINED COMPRESSIVE STRENGTH, FREEZING-THAWING, DURABILITY, AND MOISTURE ABSORPTION WERE PERFORMED ON THE SPECIMENS. SEVEN DIFFERENT GRAVELS FROM WIDELY SCATTERED GEOGRAPHICAL AREAS WERE USED IN THE INVESTIGATION. THE RESULTS HAVE SHOWN CONSIDERABLE VARIATION IN THE PERFORMANCE OF THESE MATERIALS WHEN USED IN LIME-FLY ASH-AGGREGATE COMPOSITIONS. /AUTHOR/
